Encoder emulation

Incremental encoder output (X5)

The incremental-encoder interface is part of the package supplied. Select encoder
function ROD (A Quad B) Encoder ("Encoder Emulation" screen page). The servo ampli-
fier calculates the motor shaft position from the cyclic- absolute signals of the resolver or
encoder, generating incremental-encoder compatible pulses from this information. Pulse
outputs on the SubD connector X5 are 2 signals, A and B, with 90° phase difference (i.e.
in quadrature, hence the alternative term "A quad B" output), with a zero pulse.
The resolution (before multiplication) can be set by the RESOLUTION function:
Enc. function (ENCMODE) Feedback system
ROD (1)
ROD interpolation (3)
Use the NI-OFFSET parameter to adjust + save the zero pulse position within one
mechanical turn. The drivers operate off an internal supply voltage.
The maximum permissible cable length is 100 meters.
